Fluke 438-II Series 2 Power Quality and Energy Analyzer adds key mechanical measurement capabilities for electric motors to the cutting-edge power quality analysis functions of the Fluke 438-II Series 2Power Quality Analysers. Quickly and easily measure and analyse key electrical and mechanical performance parameters such as power, harmonics, motor speed, unbalance, torque and mechanical power without the use of mechanical sensors.

Features Fluke 438-II Series 2

1. Motor torque

Calculates the amount of rotational force (displayed in lb.ft or Nm) developed by a motor and transmitted to a driven mechanical load. The motor torque is the single most critical variable that characterises the instantaneous mechanical performance of rotating equipment driven by electric motors.

2. Motor speed

Provides the instantaneous motor shaft rotational speed. Combined with the motor torque, motor speed provides a snapshot of the mechanical performance of rotating equipment driven by electric motors.

3. Motor mechanical load

Measures the actual mechanical power (displayed in hp or kW) produced by motors and provides a direct link to overloading conditions without simply basing it on the motor current.

4. Motor efficiency

Shows the effectiveness of each motor within a machine, assembly line, plant, and/or facility in converting electric power to useful mechanical work. By properly aggregating the efficiencies of a population of motors the total (aggregate) efficiency can be estimated. Comparisons to expected motor efficiencies at observed operating conditions can help quantify the cost associated with motor energy inefficiency.

How it works

Using proprietary algorithms, the Fluke Power Quality and Motor Analyser uses three phase current and voltage waveforms to calculate motor torque, speed, load and efficiency at a 1 second update rate. The motor air gap field, as observed via the voltage/current waveforms, provides the basis for the measurements. Mechanical sensors and intrusive no-load motor testing is not required, making it faster than ever to analyse overall electric motor performance.

Measure and analyze critical electrical and mechanical performance parameters, such as power, harmonics, unbalance, motor speed, torque, and mechanical power without the need for mechanical sensors. Fluke 434-II, 435-II, and 437-II Power Quality Analyzer users can add motor analysis capabilities to existing units with the Fluke-438-II/MA Motor Analyzer upgrade kit. The 438-II uses data from the motor rating plate for both NEMA and IEC rated motors to assist in the calculation of mechanical parameters.
